CZ432998A3 - Article such as stocking or stocking tights produced of fine knitted fabric with thin flat seams - Google Patents

Abstract

The seams for joining together, along the crotch, the pieces of fabric making up the article and/or for closing the toes of the legs, are made with two needle threads (F1, F2) and one looper thread (F3) that forms a chain stitch, all of them forming long stitches, in such a way that, under the stretching of the garment as it is put on, the seams become essentially "flat", that is to say very thin and certainly much thinner than they are wide.

Description

Product, such as stocking or tights, made of fine knit, with thin flat seams

Technical field

The invention relates to an article made of fine knitted fabric, such as stockings or tights.

BACKGROUND OF THE INVENTION.

Knits made on conventional overlock machines, such as Union Special machines, etc., are known in which the seams of the stitched parts are tightly pulled together (when making overlock seams), which are very thick and have a cord-like shape . This is disadvantageous both in terms of comfort and wearability of the article with respect to the irritation induced by the shape of the seams and in terms of the aesthetic appearance of the article.

It is an object of the present invention to overcome these drawbacks.

SUMMARY OF THE INVENTION

These drawbacks are eliminated by an article such as a stocking or tights, etc., made of fine knitted fabric, the seams of which are such that the seams for joining its parts along the crotch and / or closing the toe of the stocking or trousers ⁷ have a structure such that When dressed, the seams become essentially flat, ie very thin and much thinner than their width.

The product eliminates the shortcomings of the prior art and has stable seams with a satisfactory appearance. It can also be manufactured with a high degree of automation and is therefore well suited to industrial production.

In one practical embodiment, said seams are formed by two needle threads and one loop loop to form chain stitches, wherein the stitches are relatively long and do not contract.

When the pieces of knitted fabric joined by said seams are taut and aligned, their edges joined by said seams abut against each other, i.e. lie side by side and opposite each other so that the seams become thin and much thinner than their width.

According to a further feature of the invention, the article according to the invention comprises seams between its parts, which consist of three rows of stitches

namely from a first series of short stitches formed by needle thread, which are arranged transversely across the cutting line, extending from one of the two interconnected parts and entering the other of the interconnected parts at positions relatively close to the cutting edges; from the second series of longer stitches formed by the needle thread, which are also arranged across the cutting line and extend from one of the parts to be joined and enter the other at a greater distance from the same cutting line than the stitches forming the above first series of stitches the first row of stitches lies within the longer stitches of the second row of stitches; and a third row of stitches formed by loose stitches of the looper thread that are much longer and looser than the first two stitches, wherein the third row stitches form a chain seam arranged across the cutting line and forming chain stitches with the first two threads,

It follows from the constructional features described above that at

The stretch of the worn clothing expands the seam and becomes completely flat, substantially without overlapping the textile parts. This brings the distinct advantages of greater comfort and appearance. There is no disadvantageous impact on the practical and aesthetic effects that would result from the fact that the width of the flat seam obtained in this way cannot be comparable to the type of seam obtained only by hand sewing machines. Aesthetically, in the case of tights and stockings, it is already desirable that the width of the seam be limited.

BRIEF DESCRIPTION OF THE DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an overall schematic of the pantyhose of the present invention showing seams; FIG. 2 is an enlarged detail of the region indicated by the arrow f11 in FIG. 1; FIG. 2 and 4, an enlarged detail, indicated by the arrow fiv in FIG.

DETAILED DESCRIPTION OF THE INVENTION

As can be seen from the drawings, the article of the invention has flat seams of loose area stitches used to close the tips P and to join the two parts thereof, each consisting of a trouser G and a half body portion C along the crotch, possibly adding wedge T. The top seam CC is shown in more detail in Figures 2-4. In the seam region of a two-piece knitted fabric of parts L1 and L2. which are sewn together, the knit may consist of an unparalleled section I, while further the article may consist of a normal knit and is therefore more flexible and more suitable for its function using known methods.

Parallel sections I along the edges of the portions L1 and L2. The stitching areas to be stapled give the seam areas greater strength against ripping.

The flat seam described above is particularly suitable in the conditions of exposing the knitted fabric to tension when the article is worn, wherein the knit is seamed. the two seams L1 and L2 joined by seams, such as seam CP and seam CC formed by threads F1, F2 and F3, are essentially brought into contact with the edge and the edge along the cutting line T without overlapping, and in particular without stranding, that occurs with conventional seam structures produced by overlocking sewing machines. The seam may be formed such that the stitches formed by the yarns F1 and F2 lie primarily on the outside, while the stitches formed by the thread seam F3 formed by the yarn fed to the loop are on the inside of the worn article. However, it is not excluded to choose an upside-down position relative to this position.

The essential considerations to be taken into account when making a seam are what strength is required, how much extensibility is required for the stitched portions L1, L2, and what elongation is obtained by increasing the length of the long stitches and short stitches (with Fl, F2) and similar chain stitches (with thread F3).

The above-described seam can be manufactured industrially, for example, but not limited to, conventional overlock sewing machines such as Union Special, Yamato, Juki, Rimoldi, etc., which machines are equipped with a device according to the co-pending utility application. of the applicant. In this case, the seam is formed by introducing two needle threads into the overlock machine (see above).

threaded needle threads F1, F2) and one loop thread F3 of the loop. Thread F1 produces long stitches, while thread F2 will produce short stitches at an intermediate position relative to the position occupied by the long 'stitches formed by thread F1, while thread F3 leads into the loop and forms chain stitches which are particularly noticeable on the opposite side of long yarn stitches F1 and short yarn stitches F2 can be seen. The long stitches and short stitches of threads Fl and F2 can be seen in particular in Figure 2, while the stitches smyč- _r Kovac so-called chain stitches, formed by thread F3. are most noticeable in Fig. 4. The thread F1 intended for forming long stitches is fed to the needle that passes the parts L1 and L2 at a position furthest from the cutting line T, while the thread F2 is fed to the needle closest to the cutting line T.
